No, democracy is not an ideal political regime, because the forms of direct democracy are relatively rarely used in practice, the people do not directly rule anywhere, people express their preferences at elections, and their interests are represented by elected persons. The people do not have much opportunity to influence the work of the authorities. Democracy does not guarantee that voters are immune to mistakes and vote for the best. Sometimes the power goes on about the offended and dissatisfied.
Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
